Goerz Dagor and Trigor lenses

I´m curious about those Goerz lenses, but I can´t find much info on the web. Please, can you illustrate me about these lenses?. I´d like to know lens construction, image coverage angle and performance. Thanks in advance.

So many threads on Dagors and some on Trigors here. Use the search function. And so many Goerz catalogs with details out there on the web.
